During morning mass at the Vatican guest house where he lives, Pope Francis denounced those who speak of Catholicism but don't match their words with deeds.
"A Christian world without Christ at its center leads to vanity, to pride -- power for the sake of power," the pope said during his sermon.
"Words are good," he said, "but only if they are put into practice."
If the words are empty, the pope said, "they hurt, they deceive us, make us believe that we have a beautiful home, but without a foundation."
